Sitting at a table to discuss the failed trade for Jarome Iginla last Thursday afternoon, Bruins general manager Peter Chiarelli looked as if he had spent a long night in Las Vegas.

His eyes were glazed over, his voice monotone. He seemed very much like a man who had a Hall of Famer slip through his fingers.

On Tuesday, Chiarelli wore a dapper jacket and tie, refreshed and upbeat.

Trading for a 1,600-point scorer will do that to you.

On the day before the NHL trade deadline, the Bruins acquired Jaromir Jagr, the eighth-leading scorer in league history, in a trade with the Dallas Stars.

In desperate need of another goal-scorer for the stretch run, particularly after being spurned by Iginla in favor of the Penguins, the Bruins secured the most accomplished one in the league.

“His career speaks for itself,” Chiarelli said of Jagr, who has 679 goals and 1,679 points in his career. “He’s a strong player, protects the puck well, consistent with our style in the sense that there’s a cycle element to his game. He’s good on the half-wall, really good release, shot — he’s just a real good player.”

The Bruins gave up forward Lane MacDermid, prospect Cody Payne, and a conditional 2013 second-round pick in the deal. The draft choice becomes a first-rounder if the Bruins advance to the Eastern Conference finals.

The 41-year-old Jagr may not be what he was in his prime — even the distinctive mullet is gone — but he still has plenty of game left. His 26 points were the most on the Stars, and his 14 goals already make him tied for the Bruins lead with Brad Marchand.

“Obviously he’s got a ton of experience, a couple rings, he can still put points on the board,” Shawn Thornton said after the Bruins’ 3-2 win over Ottawa on Tuesday night. “I’m sure he’ll help our offense a ton.”

Jagr was one of the brightest stars for over a decade with Pittsburgh, Washington and the New York Rangers. The Czechoslovakia native has five 100-point seasons and teamed with Mario Lemieux as one of the greatest one-two combinations in league history. The Penguins won the Stanley Cup in each of Jagr’s first two seasons.

But that was in 1990-91 and 1991-92 when Jagr was still under legal drinking age. Now at twice that age, the Bruins aren’t expecting the same player.

Chiarelli likened the move to the Mark Recchi acquisition at the 2009 trade deadline. Recchi, who was also 41 at the time, was an accomplished player from the early 1990s Penguins wrapping up a Hall of Fame career. He accepted a job as a role player with the Bruins and finished his career two years later with a third Cup.

“I actually asked him that, and he was fine with it,” Chiarelli said. “He wants to win, and as you progress in years, your skill set and other things deteriorate, they lessen. … I think I’m confident that Jaromir will accept whatever role he’s given, and he knows that he’s coming into a strong group, and he’ll help us out.”

Jagr could slide into a top-line role as the right wing next to Milan Lucic and David Krejci. Alternatively, Jagr could slot into the third-line wing role the Bruins have been unable to fill all season.

Patrice Bergeron left Tuesday’s game after taking an elbow/forearm to the head in the second period and didn’t return. If he misses time, that could change where Jagr slots in.

Jagr will certainly give a boost to a power play that’s once again slumping; the Bruins are 1 for 19 in the last nine games. The Bruins have used several right-hand shots (Tyler Seguin, Rich Peverley, Patrice Bergeron) on the left-side half-wall on the power play; the left-handed shooting Jagr would be a more natural fit in that spot.

“That’s one of the things, he’s a strong half-wall player on the power play,” Chiarelli said. “He can roll off the top of the circle and really fire that wrist shot, and he can make plays. That’ll help us on the power play.”

Coach Claude Julien will have to determine the puzzle pieces in the next few days. Jagr is expected to make his debut Thursday against the Devils.

Jagr is on a one-year, $4.5 million deal. He’ll be an unrestricted free agent this summer.

The Bruins still remain about $5.9 million under the salary cap (nearly $10 million if they place Marc Savard on long-term injured reserve), and could make another move before Wednesday’s 3 p.m. deadline. Chiarelli said the Bruins will remain in the loop on other players, leaning more towards a defenseman.
